Why did all my photos disappear?

Unfortunately, while trying to upload a new photo, my ENTIRE photo album disappeared and/or was deleted. I have NO IDEA how that happened. I clicked UPDATE, and when I went to view the page…it was blank!!

What happened? Is there ANY way you can restore this page without my posting every single photo again? I had more than a dozen photos posted!!

I’m REALLY upset about this. It took me a long time to get that page the way I wanted it!
